Agustín is the author of the beautiful book Birds of Península Valdés:
“For visitors to the Peninsula Valdes, site of a famous Magellanic Penguin colony, swirling clouds of Red Knots, and the enigmatic Magellanic ‘‘Plover,’’ this book is a long-awaited and stunning photographic introduction to the peninsula and coastal Chubut Province. The gorgeous photos delight the eye for their artistic beauty and composition, offer accuracy for help in identifying species encountered, and capture spectacular behavioral displays. The book’s emphasis is on the birds of the area, but the keen naturalist author could not resist tossing in photos of several mammals and herps as well. Painstaking search of the literature and records of museum specimens, published sightings, eBird, and personal correspondence makes this volume a valuable, updated documentation of the Valdes/Chubut avifauna.”
“This highly informative and beautifully photographed book greatly expanded my knowledge of a biological wonderland and sets a new standard for regional guides. It makes me eager for a return visit.”
